摘要：

A highly efficient protocol to access carbazole from donor acceptor cyclopropane and indonyl alcohol via [3+3] annulation in the presence of a Lewis acid has been demonstrated. This method facilitates the post functionalization of the substituted carbazole into a fully conjugated pi-system exhibiting intense emission bands in the visible range of the spectrum and also offers a convenient route toward the synthesis of pityriazole derivatives.
